摘要

Grid computing has contributed to advances in computational and communication technologies making economically feasible the conglomeration of multiple clusters of heterogeneous networked resources and services which, in turn, has lead to the development of large-scale distributed systems It is in this context that available resources are allocated to where a company, research center, or industry needs them most However, available resources may be limited We propose a secure delivery and billing protocol between service provider and service requester designed not only to ensure that the communication protocol be subject to no malicious attacks but also to provide billing authentication for business transactions Our approach can be used within a wide variety of applications with relatively few modifications to the super-peer protocol while only causing slight, readily ignorable increases in traffic
